Hello. How can I place a family along a polycurve in Dynamo, ensuring that each instance is oriented outward and aligned at a parallel angle to the curve? Thanks ![Set_FamilyInstance_Curve](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/d/f/df5e0e5bceb01cb15d568bbe39687f4431bdabab.png) ![Screenshot (47)](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/3/7/375f0ae2fa193fe24f7a1f483106f3c46a76a765.png) ![Screenshot (46)](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/6/7/674139875b1e2bf6c82bb5899cb559dc671d198a.png) ---

Hi @yaseminV2XL5 try normal at parameter, so you can get the right vector on the curved curves ---

Hi @sovitek. it’s not working on me. Where am i going wrong ? ![A01](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/2/8/283940d180c5bde6b07c5c2de6879351823ccf3e.png) ![A02](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/a/0/a0a9718ef2f4d38e8d5f987ba34133790b569029.png) ---

Hi try join your curves ---

It doesn’t work either. ![Screenshot (49)](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/4/7/4719e52e4a11fdb01c2bf30b8f6681cbc3176e62.png) ---

have you joined the curves ? can you share a rvt with that family ---

yeah but the issue is your curves dont have same direction i guess, so join them first and try an explode, but you are welcome to share for a test ---

You are right. if it is Polycurve, your lines work. But my Curves dont work still. ![Screenshot (50)](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/d/3/d3c670221d97c79b2858e251e462872742df74bf.png) [V.rfa](https://forum.dynamobim.com/uploads/short-url/nczfbd64qAuCc0rWmvc16OrNqYz.rfa) (680 KB) ![A03](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/9/f/9fa4bfb03a7a6a688e23092961daffcb49dcb1c8.png) ---

Yours are all consistently oriented inwards, which indicates they curve is going ‘backwards’ (in as much as a closed loop can go the wrong way) relative to your needs. Try adding a Curve.Reverse before you generate the coordinate systems. ---

yeah all what Jacob say 😉 ) thats the issue, here is another dirty way there probably could work as well…just a fast one…can be made much more elegant…but dont have time, and i just play around 😉 😉 ![Skærmbillede 2025-11-19 090925](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/1/3/13c0dd8a2588b4192b203d23fe7dfe20c7d7bbe8.png) [testffff.dyn](https://forum.dynamobim.com/uploads/short-url/qwTcyLo9e50TsWe7rKf0J1PqUmI.dyn) (54.8 KB) ---

Hi @sovitek . It’s not as dirty as yours, but it’s still a different kind of dirty road.😁 Thank you @sovitek and @jacob.small . You really helped me solve the problem. ![Set_FamilyInstance_Curve](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/4/b/4badaf5c6ba26aaa6e035998a68768678457283a.png)
